DE Problem

Hi I'm a newbie and i have a problem here that i cannot solve, or i don't know how to solve. Hope you experts can help me out!
Here it is:A tank contains 10 kg of sodium hydroxide in 1000 litres of water. Water is continuosly added to the tank at a rate of 5 litres/min so that the mixture is diluted evenly. At the same time, the solution flows out at the same rate. Initially, there were 10 grams of sodium hydroxide in every litre of water. How long will it take for the concentration of the solution to drop to 3.2 grams per litre?

Hello Kanki. You know, you need to show a little work dude. It's best for you that way don't you think? Just make some attempt at solving it, anything, just move the numbers around the paper randomly, whatever, and show us what you did and explain what you think should be done. Here's one we worked on earlier (click on the link below). I bet a dollar if you follow it closely, you can figure out yours. Try it, then come back and say, "look, I tried to do this one, here's what I did <insert something here, anything>. Can you guys explain where I'm going wrong?" Or someone may just solve it. Well, what I said is what the general policy is anyway.
